Question 1 of 5
Which of the following types of cells is the immune system's shutoff mechanism?
Correct Answer: B
Rationale: Suppressor T cells, also known as regulatory T cells, play a critical role in regulating the immune response by acting as the immune system's shutoff mechanism. These cells help maintain immune tolerance and prevent overactivation of the immune system, thereby preventing autoimmune reactions and excessive inflammation. Suppressor T cells exert their immunosuppressive effects by inhibiting the function of other immune cells, such as effector T cells and B cells, and helping to control the overall balance of the immune system.
Question 2 of 5
The nurse is taking vital signs of a pregnant woman during her first prenatal visit. The patient asks the nurse if she has to have an HIV test. Which of the following is the nurse's best response?
Correct Answer: D
Rationale: The nurse's best response is D, "After voluntary pretest counseling, you decide whether HIV testing should be done." It is important for the pregnant woman to make an informed decision about HIV testing after receiving pretest counseling. The decision should be based on her individual risk factors, concerns, and preferences. The nurse should provide information about the importance of HIV testing during pregnancy, the benefits of knowing one's HIV status, and the available treatment options if the test is positive. Ultimately, the decision should be made by the pregnant woman after considering all the information provided.
Question 3 of 5
Following a splenectomy, a client has a hemoglobin (Hb) level of 7.5g/dl and has vertigo when getting out of bed. The nurse suspects abnormal orthostatic changes. The vital sign values that would most support the nurse's analysis are:
Correct Answer: C
Rationale: Following a splenectomy, the client's hemoglobin level of 7.5g/dl indicates anemia, which can contribute to orthostatic hypotension. When the client changes position from lying to standing, the decrease in blood volume may lead to a drop in blood pressure. Additionally, the compensatory mechanism to maintain perfusion to vital organs is to increase the heart rate. Therefore, the vital sign values that would most support the nurse's analysis are a drop in blood pressure (hypotension) and a rise in heart rate (tachycardia).
Question 4 of 5
For a client diagnosed with idiopathic thrombocytopenic purpura (ITP), which nursing intervention is appropriate?
Correct Answer: B
Rationale: The appropriate nursing intervention for a client diagnosed with idiopathic thrombocytopenic purpura (ITP) is administering platelets, as ordered, to maintain an adequate platelet count. ITP is a condition characterized by a decrease in platelet count, which can lead to thrombocytopenia and an increased risk of bleeding. Administering platelets can help prevent excessive bleeding and maintain hemostasis in these patients. Platelet transfusions may be required in severe cases to raise the platelet count to a safe level and prevent bleeding complications. It is crucial for nurses to monitor the platelet count regularly and administer platelets as prescribed to manage ITP effectively.
Question 5 of 5
A client has had heavy menstrual bleeding for 6 months. Her gynecologist diagnoses microcytic hypochromic anemia and prescribes ferrous sulfate (Feosol), 300mg PO daily. Before initiating iron therapy, the nurse reviews the client's medical history. Which condition would contraindicate the use of ferrous sulfate?
Correct Answer: D
Rationale: Severely impaired liver function is a contraindication for the use of ferrous sulfate. In patients with liver disease, iron metabolism can be affected, leading to potential toxicity from iron accumulation. Ferrous sulfate is primarily metabolized by the liver, so in cases of severely impaired liver function, the metabolism of the drug may be altered, leading to potential adverse effects. It is important to consider alternative iron therapy options in patients with severe liver impairment to avoid potential complications.
